Scientists have revived activity in the brains of pigs up to nearly an hour after circulation had ceased. In some cases, functionality was sustained for hours through a surprising discovery by researchers in China.

This achievement represents a huge step forward in working out how to restore brain function after a patient has suffered a sudden cardiac arrest. It suggests that doctors may be able to widen the brief window for successful resuscitation of patients following cardiac arrest.

The trick? Incorporating the patient’s unharmed liver – the organ the body uses to purify its blood – into the life support system used to revive the brain after the time had elapsed.
